While on patrol in the Norwegian Sea, HMS Viking fires from 600 yards a four-torpedo spread at the German submarine U-965. The Germans saw the torpedo tracks and managed to avoid them.

A serving W/T aboard Viking at this time recalls that the topedoes fired "porpoised", allowing them to be seen by the crew of the U-boat, which then dived. He said they had no idea why the U-boat was on the surface as it evidently was not disabled. He also noted that the crew of the Viking weren't sorry they'd missed the other submariners.
